5175 Newtons

Explanation:

We are given;

Mechanical advantage is 15 Output force is 345 N

We are required to calculate the work input;

We need to know that mechanical advantage is the ratio of output force to input force. That is, mechanical advantage = Output force : input force Rearranging the formula;

Input force = Output force : Mechanical advantage

Therefore;

Input force = 345 N * 15

= 5175 Newtons

Thus, the work input of a pulley system is 5175 N
